“…Due to monoculture practice and recurrent pesticide application in the field, insect pests gradually become resistant to insecticides (Ray 2022). Then, recombinant DNA technology is used to modify plant genes and create transgenic seeds with desirable traits (Samal, Rout 2018).…”

Agriculture has played an important role in human life, both for sustaining life and livelihood. The population explosion has necessitated huge agricultural production. Consequently, there has been modernisation of agriculture not only in farming practices, but also in introducing improved agricultural implements, irrigation, chemical fertilisers, synthetic pesticides, and high-yielding seeds. Agricultural intensification and monoculture make it possible to increase crop production, to a large extent gaining food security, but paying no or little attention to environmental well-being. Intensive tillage leads to soil erosion, nutrient loss, and soil organic carbon loss, which affects the soil biota. Extraction of underground water for irrigation causes groundwater levels to drop and hinders aquifer recharge. Monoculture and the cultivation of high-yielding crops lead to the loss of many indigenous crop varieties and the prevalence of pests and pathogens. Extensive chemical fertiliser application can cause soil acidification, eutrophication, and nitrate contamination in groundwater through leaching. Indiscriminate use of pesticides is a potential threat for non-target organisms, including humans. The agriculture sector contributes a considerable portion of greenhouse gases to the atmosphere. Therefore, the only way to protect our mother earth and create a healthy environment is through sustainable agriculture to ensure food safety and security.

“…In terms of disease resistance, as diseases can significantly reduce the yield and quality of vegetable crops, researchers seek to identify and introduce disease resistance genes to increase crop resistance to specific pathogens (Samal and Rout, 2018). Furthermore, with the increasingly significant impact of global climate change, the stress tolerance of vegetable crops, such as drought, heat, and salt-alkali tolerance, has also become an important target for genetic improvement.…”

The application of Genome-Wide Association Studies (GWAS) in the field of vegetable crop genetic improvement has matured, providing powerful tools to elucidate the genetic basis of traits such as yield, nutritional value, disease resistance, and adaptability. This review explores the role of GWAS in vegetable crop genetic improvement, particularly in identifying key genetic markers to enhance yield and improve nutritional value. By analyzing current research progress, this study discusses how GWAS aids scientists in precisely locating genes or genomic regions controlling significant agronomic traits, thereby optimizing breeding strategies and enhancing crop performance. The research also addresses the technical and methodological challenges faced in genetic improvement, as well as future directions, including the integration of multi-omics data and gene-editing technologies to accelerate the improvement of vegetable varieties. This study aims to distill key insights by comprehensively analyzing the application of GWAS in vegetable crop genetic improvement, providing a scientific basis for future research directions and their profound impact on the field of agricultural genetics.

“…High yielding varieties in agriculture augment production by increasing per acre yield, consequently improving self-sufficiency and decrease dependency on imports. However, cultivation of high-yielding varieties is a chemicalintensive program with substantial requirement of both chemical fertilizers and pesticides (Samal & Rout, 2018). In recent years, more consideration has been given to the use of biofertilizers and their integration, to not only have high plant yields but also to cut the usage of environmentally unfavorable chemical fertilizers (Akhtar, Siddiqui, & Wiemken, 2011).…”

The present study was intended to investigate individual and interactive effects of Funneliformis mosseae (an arbuscular mycorrhizal fungus) and Rhizobium (a root nodulating bacterium) on growth and yield of groundnut growing under natural conditions. Plants growing in arbuscular mycorrhiza (AM) and/or Rhizobium inoculated soil exhibited superior growth, fitness and yield. Improvement in plant growth due to microbial inoculations had a significant correlation with their response to mycorrhization, relative water content, chlorophyll content, nutrient uptake, and antioxidant activity. The increase in all parameters except N acquisition and protein concentration was significantly higher on the formation of AM than rhizobial inoculation, albeit their combination displayed synergism to uplift metabolism and yield of host legume. Thus, the study indicated that synergistic behavior among microorganisms (AM and Rhizobium) had the most affirmative effects on the growth and harvest index of groundnut variety-TG37A and helped plants to thrive better in soils without chemical fertilizers. Contribution/Originality: This study contributes to the existing literature of tolerance aptitude of groundnut variety-TG37A against existing adverse environment. This study also documents the importance of AM and Rhizobium in improving the growth and metabolism of this variety. 1. INTRODUCTION Arachis hypogaea, an annual oil yielding plant of Fabaceae family, is one of the most important cultivated food legume (rank second) and edible oilseed crop (rank fourth) in world (Yol, Furat, Upadhyaya, & Uzun, 2018). However, biotic diseases and extremes of abiotic factors like temperature, drought, and soil salinity in semi-arid tropics are the severe limitations affecting both groundnut yield and excellence. In addition, impending climate change, poor agronomic practices, and inadequate inputs have further accentuated these harmful impacts (Krishna,
